I wouldn't put much weight in the enduro mag test findings - the results don't make any sense. I see a few issues: 1. Shimano XTR, XT, and SLX all have the same mechanical and hydraulic power output, but the test results show them as being wildly different. 2. They also show TRP DHR evo as dramatically underperforming XTR. Having used both, this is just incorrect... 3. And lastly, XTR being next to Maven in terms of test results in laughable. XTR is a cross country brake compared to maven stopping power. Based on the wild discrepancy between mechanically equal...

It's not a knowledge or concept problem. It's an attitude problem. PVD is TOXIC.

Rulezman, Jan Heine, PVD, Grant Peterson... cycling seems to perversely reward people with big egos, big opinions and questionable applications of scientific principles.

You mean low QI 😉😂😂😂

Comparison of bars with rise modeled in. Both have a similar max load. 35 mm bar is on top and 31.8 mm bar is on bottom. Bending moment is at its maximum on the inboard end and zero at the free end so I think it makes sense that the stiffness of the innermost section of bar is quite influential in terms of deflection. It's worth noting that, while the approximate 0.05" difference in deflection is a little more than 10%, we're still only talking about 0.05" difference. Thin vs. thick grips would easily take up that difference. Ultimately you...

Tomorrow I’ll whip up some sort of comparison. Deflection can be analyzed by integrating across the width of the bar so if the outer 75% of a 35 mm bar were identical to a comparable 31.8 mm bar, the deflections would be identical over that length and the only difference would come down to that innermost 25%.

Correct they are thermosets, most are very, very stiff in compressive loading situations, >30ksi. Just as stiff as the aluminum caliper under similar compressive loadings. The only reason there would be impressions and deformations in the phenolic piston blocks is due to poor design leading to stress raisers that allow for point loading putting the material into a plastic deformation condition above typical elastic conditions. I personally have never seen such issues with the phenolic inserts in my Hopes, and I have yet to ever hear of anyone mention it before. I don't have a stress-strain curve for Bakelite or...
